Definitions

  • the present invention relates in general to devices for evaporating volatile substances, in particular for volatile substances having complex chemical compositions for example some types of perfumes and/or insecticides.
  • the present invention refers to a reinforced membrane structure, in which a semi-permeable membrane is laminated with a fibrous laminate or a capillary laminate.
  • Evaporator devices for volatile substances are very well-known, for diffusing air fresheners, pesticides or similar chemical substances.
  • this kind of membrane product use to come with a barrier top aluminium layer that has to be pealed off before first use.
  • these materials use to have already quite lower mechanical resistance vs polyolefins, that could be even lower due to the chemical solubilisation. This may provoke a membrane rupture when aluminium is peeled off.
  • One object of this invention is to solve the previously described drawbacks of the prior art, in a simple and economic manner.
  • the invention provides a multilayered structure for a membrane, which comprises a thermoplastic fibrous laminate bonded to a monolithic vapour permeable membrane.
  • fibrous laminate is to be understood as any type of thermoplastic material having a capillary or porous structure, and which strength is suitable to act as a substrate to reinforce the membrane.
  • the invention also refers to a manufacturing process of the device, in which the multilayer membrane is welded to a container in such a way the thermoplastic fibre structure is erased completely by the welding and a monolithic film of the material is created in the welding area.
  • Fibrous laminate is placed on the inner side of the container. Fibre structure is erased in the area of welding in order to avoid liquid can pass between container and membrane.
  • the container with the multilayered structure according to the present invention can be used in conjunction with any type of device for evaporating volatiles substances, for example an evaporating device incorporating heating means or using a forced flow of air to enhance the evaporation.
  • the fibrous laminate is:
  • thermoplastic material made from a thermoplastic material, optimally completely of thermoplastic material has a melting point lower than the membrane material.
  • the membrane is mechanically reinforced by the fibrous laminate, avoiding thus the wrinkles and increasing the strength that the membrane can support, and thus reducing the possibility of rupture when the top barrier material is peeled off.
  • the lamina is fibrous it has capillary properties, for that the fibrous laminate distributes liquid all over the internal surface of the membrane with the liquid. This way, it is assured that 100% of the evaporation surface of the membrane is used at any time.
  • fibrous lamina is porous, it does not represent any limit to liquid transport through the membrane.
  • FIG. 1 shows a perspective view of a schematic representation of the multilayered membrane of the invention formed by a thermoplastic fibrous laminate bonded to a monolithic vapour permeable membrane, and drawing (b) is a similar representation than figure (a) with a removable barrier film over the membrane, and provided above a container prior to the welding process.
  • FIG. 2 drawing (a) is an schematic elevational view of the membrane structure placed above a container prior to the welding process, and drawing (b) is a similar representation than drawing (a) once the membrane structure has been welded to the container.
  • FIG. 3 shows schematically the effect of the manufacturing process of the invention, wherein drawing (a) shows a plan view of a sealing flange of a sealing tool used for welding the multilayered membrane to a container; drawing (b) shows a plan view of the multilayered membrane before welding; and drawing (c) shows a plan view of the multilayered membrane after welding, wherein it has been represented how the area of the membrane to which the sealing flange has been applied has a different appearance because the fibrous material is erased because it has been fused.
  • the device for evaporating volatile substances of the invention in a preferred embodiment, comprises a container ( 6 ) of a liquid volatile substance ( 8 ), with an opening ( 10 ) and at least a part of the container in the periphery of said opening made of a thermoformed material.
  • the device further comprises a vapour permeable membrane ( 1 ) and a thermoplastic fibrous laminate ( 2 ) bonded together, so that the container is closed by said vapour permeable membrane ( 1 ) and the fibrous laminate ( 2 ), in such a manner that the fibrous laminate ( 2 ) is welded to the thermoformed part of the container.
  • a film of a sealing material ( 7 ) compatible with the fibrous laminate, is provided on the internal surface of the container and on a perimetral lip ( 11 ) of the container around the opening ( 10 ).
  • the sandwiched structure formed by the membrane ( 1 ), laminate ( 2 ) and barrier ( 3 ), is placed on the perimetral lip ( 11 ) closing the container as shown in FIG. 2 b , so that the laminate ( 2 ) is arranged internally to the container.
  • heat and pressure is applied by a sealing flange ( 4 ) of a sealing tool, to the periphery of the membrane structure, until the perimetral part of the thermoplastic laminate fuses with the container forming thereby a sealing ring ( 9 ), which prevent any liquid leak to the outside.
  • the area of the fibrous laminate that has been erased in the welding process change its visual appearance and this effect is used in the present invention to determine the quality of the welding process.
  • FIG. 2 shows the container in a non-operative position (horizontally). However, in use the device, would the place in another position (for example vertically) so that the liquid volatile substance ( 8 ) is in contact with the fibrous laminate ( 2 ) and it can evaporate through the membrane.
  • the membrane is a monolithic membrane with elastomeric behaviour, for example an elastomeric polyester, polyamide block ether or polyurethane or Polyolefin elastomer.
  • the fibrous substance can be whatever fabric made of a thermoplastic material (a plastic that can be molten).
  • the laminate is a non woven material, or a polyolefin non woven, or a PP or PE non woven, or an hybrid PP/PE non woven where fibre has a PP core and a PE shell.
  • the laminate may consist of a laminate of open foam.
  • the lamination between the membrane and the fibrous material can be done without any adhesive, by thermally/mechanically bonding the two layers, but preferably, the adhesion is done by applying an adhesive.
  • the adhesive is applied in a discrete form (not a continuous layer), by points, or by lines, in order to avoid the adhesive decrease the permeation speed (acts as a barrier).
  • the adhesive may also be applied in the form of a thin continuous layer of adhesive made of material permeable to the volatile substance.
  • the container is made of a thermoformed material, wherein the upper layer of this material is made of a material compatible with the fibrous laminate.
  • the fibrous laminate is a non woven made of PE or hybrid PP/PE (as described above)
  • the upper layer of the container will be done of PE as well.
  • the device also incorporates an aluminium foil ( 3 ) with a plastic layer on the side of the membrane, that is partially compatible with the membrane material, that means, that can bonds to the membrane but not in a permanent way.
  • the aluminium foil ( 3 ) avoids evaporation of the volatile substance before the first use.
  • Membrane is a polyester elastomer of 70 microns thickness.
  • Adhesive is a poluyrethane solventless based adhesive applied in crossed lines.
  • Non woven is a PE spunbound non woven of 50 g/m2.
  • Thermoformed container is made of PET/EVOH/PE.
  • Membrane is a polyester elastomer of 70 microns thickness.
  • Adhesive is a poluyrethane solventless based adhesive applied in a thin continuous layer.
  • Non woven is a PE spunbound non woven of 50 g/m2.
  • Thermoformed container is made of PET/EVOH/PE.
